added very simple pos tagger (postagger.py)

postagger.py

+import nltk
+from nltk.tokenize import word_tokenize
+from corpus import read_corpus
+
+corpus = read_corpus("corpus.csv")
+tagged_corpus = []
+
+# for debugging purposes. if you're sure it's worth it, use
+# for i in range(len(corpus)):
+for i in range (9):
+    tagged_corpus.append(nltk.pos_tag(word_tokenize(str(corpus[i]['REVIEW']))))
+
+print (tagged_corpus)
